I've been using Lysol products for many years. I've always been satisfied. That being said, this Cling gel is the worst bowl cleaner I've ever used by a WIDE margin. It leaves more stains & marks from the product after use, than what you were trying to clean!! Yes, I did follow the directions, which make no sense, compared to any other bowl cleaner. You are supposed to flush right before you use it. I'm assuming this is to help minimize the staining the product causes. How about if I just use a bowl cleaner that doesn't stain white bowls? A home made mix of bleach & water works tremendously better than this product. If you let this soak for more than a minute, let alone 15 like the directions say you can, I hope you have lots of free time to get your blue stains off your bowls. I'm so happy I bought a box of 4 at Sam's Club of this awful cleaner. I had never used it before I saw it at Sam's, but I figured, "Hey, it's from Lysol, it's got to be pretty good". What a mistake that was! I wish I could give this stuff negative 5 stars!
